I am running Geographically Weighted Regression and originally was using ArcGIS to carry out the analysis until I read/heard mixed reviews about it. I have now tried a different programme to run it (SAM) and get different results.
Does anyone know what the spatial weighting function is in ArcGIS? I think it is Gaussian but am not 100% sure. I cannot select this with Arc but there are different options to chose from with SAM.
